7 Claims. (Cl. 158-115) My invention relates to improvements in lightersfor gas burners, and it consists of the combinations, constructions andarrangements hereinafter described and claimed.

The pilot lights for gas burners are generally placed within the burnercasing, and this not only makes it hard to see the light, but it furthersubjects the lighter to the extreme heat given oli by the burner.

The principal object of my invention is to provide a lighter which isdisposed outside of the burner casing where it may be readily accessibleto the operator. The lighter makes use of a jet having a small oriicefor directing a stream of gas over the main burner when the Valvecontrolling the iiow of gas is open. I prefer to use a push button typeof valve which will automatically cut oif the gas in the lighter whenthe push button is freed.

The gas issues from the oriiice with considerable force, and when thisgas is ignited by means of a match, the iorce of the gas issuing fromthe jet will cause the name to blow out. In order to overcome this, Idispose a shield in front of the orifice, having an opening slightlysmaller than the diameter or" the stream of gas passing through theopening. The jet orice is placed slightly above the center of theopening in the shield and this will cause a certain portion of the gasto be deiiected upwardly. A deecting hood conveys this deiiected streamof gas upwardly and away from the burner casing, and this gas may beignited and will in turn ignite the gas passing through the shieldopening and over the burner. The shield continues to slow up the portionof gas striking it, and this portion mixes with air to form acombustible mixture which will keep burning, and the ame from thismixture will ignite the gas passing through the opening in the shieldand prevent the flame from blowing out.

Other objects and advantages will appear in the following specication,and the novel features of the device will be particularly pointed out inthe appended claims.

My invention is illustrated in the accompanying drawing forming a partof this application, in which Figure 1 is a horizontal section throughthe lower part of a heater, showing the main burner and my deviceoperatively applied;

Figure 2 is a front View of a heater showing the device in place;

Figure 3 is a top plan view of the device;

Figure 4 is a vertical section through the device; and

Figure 5 is an end view of the device.

In carrying out my invention, I make use of a heater casing l, (seeFigure l), having a main burner 2 disposed near the bottom o1" thecasing. Figure 2 shows an opening 3 provided in the casing wall and aplate l movably secured to the casing that supports a main gas pipe 5,which commtmicates with the main burner 2. My gas lighter, indicatedgenerally at 6, is secured to the plate 4 and is positioned so as todirect the pilot flame through the opening 3 and over the main burner.

I will now described the device in det-ail. Figure i shows the lighteras having a base '7, with a gas jet 8 projecting above the base. Agas-deflecting shield 9 extends upwardly from the base and has anopening 10 in its vertically-extending wall.

rihe jet 8 has a small orice l1 facing the opening l0, and it will benoted from Figure 4 that the axis a of the orice 11 is disposed abovethe axis b of Vthe opening l0.

The gas,

in issuing from the orifice 11, forms a cone, and the cross section ofthis cone at a point adjacent to the opening 10 is slightly larger thanthe opening.

Moreover, since the orifice 11 is disposed above the center of theopening 10, a small portion of the gas will strike the inner surface ofthe shield 9.

The force of the gas which the gas issues.

The operator ignites the stream of gas issuing from the opening 14. Dueto the combustible mixture of this gas', the flame will instantly carrydown to the opening 10 where it will ignite the gas passing through theopening. So long as the gas issues from the oriiice l1, a combustiblemixture will be formed in the curved portions 13, and this mixture willkeep on burning and will continue to ignite the gas ilowing through theopening 10.

In this way,

the name is prevented from being blown out.

The base '7 has side wings 15 that extend from the jet 8 to the shield9. These wings cooperate with the curved portions 13 for forming apassageway for the gas. be dispensed with.

Ii desired, the wings may The lighter is secured to the plate 4 by meansof a bolt 16, (see Figure 2), passed through an opening 17 in adepending lug 18, (see Figure 4), and into the plate.

It will be noted from Figure l that the main gas pipe 5 has a mainburner valve 19 and that a by-pass pipe 20 leads from the pipe 19 to thejet 8. The pipe 20 is provided with a push button valve 21.

From the foregoing description of the various paits of the device, theoperation thereof may be readily understood.

When the operator desires to light the main burner, he manuallydepresses the push button 21 and this opens the push button valve sothat gas will flow out through the jet orice 11. As already stated, aportion of this gas will pass out through the opening 14, and theoperator can ignite this portion. The main stream of gas issuing fromthe opening 10 will instantly be ignited, and the burning gas in thecurved portions 13 will continue to keep the main stream of gas ignited.The main stream of gas has enough pressure for causing a llame '7 to 10inches in length to issue from the opening 10.

After the gas from the opening 10 is lighted, the operator can open themain burner valve 19, and the gas issuing from the entire burner will beinstantly ignited instead of only a sniall portion of the gas beingignited as is now the case. When the main burner is lighted, theoperator can free the push button 21 and the pilot light will beextinguished.

While have shown only the preferred form of my invention, it should beunderstood that various changes or modifications may he made within thescope of the appended claims without departing from the spirit of theinvention.

I claim:

l. A gas lighter comprising a supporting base, a gas jet carried therebyand having an orice in its side wall, a deector disposed in the path ofgas issuing from the orifice and having an opening whose center isdisposed slightly below the center of the orifice, the axes of theorince and opening extending parallel with respect to each other, thesides of the delector being curved in- Wardly and the top of thedeflector being provided With a hood.

2. A gas lighter comprising a supporting base, a gas jet carried therebyand having an orifice in its side wall, a deeotor` disposed in the pathof gas issuing from the orice and having an opening whose center isdisposed slightly below the center of the orifice, the sides of thedeflector being curved inwardly and the top of the deilector beingprovided with a hood, and side wings extending from adjacent the jet tothe sides of the deflector.

3. A gas lighter comprising a jet having an opening, a gas deflectorplaced in the path of the gas issuing from the jet and having an openingfor 'permitting the greater portion of the gas to pass therethrough, thesides of the deector being curved for forming air and gas-mixing spaces,a hood formed in the top of the deflector, and wings extending fromadjacent the jet to the deflector.

5. A gas lighter comprising a jet having an orice, a shield facing theorice and having an opening whose axis is parallel with the orice axisand spaced slightly below.

6. A gas lighter comprising a jet having an orice, a shield facing theorifice and having an 11 opening who-se axis is parallel with the oriceaxis and spaced slightly below and means for protecting the now of gasagainst cross drafts as the gas passes from the orifice to the shield.
